| 摘 要： | 在简单回顾奇异值法压制随机噪音的基础上,提出了基于奇异值分解的f-x-y域滤波方法。该方法是一种三维去噪方法,它不需求取同相轴的倾角就可以去除倾斜同相轴的随机噪音,同时还可以较好地保持地震信号的振幅。经理论模型试算表明,该方法运算速度快,效果明显,是一种可行的去噪方法。

| Abstract: | Based on an analysis of the SVD method, the authors advance a filtering method based on singular value decomposition in f-x-y domain. The method is a true three demension. With this technique, it is not necessary to know the dip of the event when the random noise is eliminated. In addition, the amplitude of the event can be preserved. The results of data simulation show that, with its rapid operation time, this method is very effective. |
